FCA US LLC is recalling an estimated 467,480 SUVs worldwide because faulty fuel pump relays may lead to problems starting the engine, or problems with the engine stalling, in 2012 and 2013 model-year Dodge Durango SUVs.

The recall also includes 2011 Jeep Grand Cherokee SUVs sold outside of North America.

The recalled vehicles are equipped with 3.0-liter diesel engines. Current vehicles with EcoDiesel engines are not affected, the automaker said. The recall will allow dealers to install a new relay circuit that improves fuel pump relay durability.

FCA US engineers discovered the problem after recognizing a condition identified in a previous investigation that prompted an earlier recall. Fuel-pump relays susceptible to deformation can prevent a vehicle from starting or can lead to engine stall.  

Of the two scenarios, the no-start condition is the more common, the automaker said. FCA US added it is unaware of any related injuries or accidents.  

The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. But none of these other functions, including air-bag deployment, is affected by the fuel-pump relay, FCA US said.

The new recall campaign affects an estimated 338,216 vehicles in the U.S. A total of 18,991 are in Canada. Additionally, 10,829 are in Mexico and 99,444 are outside the NAFTA region.   

FCA US will advise affected vehicle owners when they may schedule service, which will be performed at no cost. In the interim, customers who experience a no-start condition or engine stall are advised to consult their dealers.
